Thank you for testing, but I'm not sure using only the NO_REPORT_OPCODES quirk is wise here, the other similar La Cie drive also started out with just that quirk, only to have the NO_SAME quirk added later. See: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=8010622c86ca5bb44bc98492f5968726fc7c7a21 Actually triggering a WRITE_SAME SCSI command is likely tricky, so it likely requires a special workload to ensure that that flag is not necessary. As Oliver set with the quirk to disable UAS we at least have the drive working (albeit slower then it would work with UAS) so we can take our time to make sure that things work properly with the combination of the f+k flags (at least using both seems best to me) before re-enabling UAS.
